Laptop touchpad acts weird in firefox

I just installed Fedora 7 on my laptop and when I'm in a web browser or similar if I use a quick up/down motion on the pad it makes the page go back/forward accordingly.

Is there a way to disable this? I think I need to change something in my xorg.conf, but I have no idea what to change/add.

So here it is:

Code:

# Xorg configuration created by pyxf86config



Section "ServerLayout"

        Identifier    "Default Layout"

        Screen      0  "Screen0" 0 0

        InputDevice    "Keyboard0" "CoreKeyboard"

        InputDevice    "Synaptics" "CorePointer"

EndSection



Section "InputDevice"

        Identifier  "Keyboard0"

        Driver      "kbd"

        Option            "XkbModel" "pc105"

        Option            "XkbLayout" "us"

EndSection



Section "InputDevice"

        Identifier  "Synaptics"

        Driver      "synaptics"

        Option            "Device" "/dev/input/mice"

        Option            "Protocol" "auto-dev"

        Option            "Emulate3Buttons" "yes"

EndSection



Section "Device"

        Identifier  "Videocard0"

        Driver      "intel"

EndSection



Section "Screen"

        Identifier "Screen0"

        Device    "Videocard0"

        DefaultDepth    24

        SubSection "Display"

                Viewport  0 0

                Depth    24

        EndSubSection

EndSection

I *think* you need to add:

Code:

Option "HorizScrollDelta" "0"

to this section:

Code:

Section "InputDevice"

        Identifier  "Synaptics"

        Driver      "synaptics"

        Option            "Device" "/dev/input/mice"

        Option            "Protocol" "auto-dev"

        Option            "Emulate3Buttons" "yes"

EndSection

Code:

Section "InputDevice"

        Identifier  "Synaptics"

        Driver      "synaptics"

        Option            "Device" "/dev/input/mice"

        Option            "Protocol" "auto-dev"

        Option            "Emulate3Buttons" "yes"

        Option      "HorizScrollDelta" "0"

EndSection

This will disable the horizontal scrolling that (I think) is causing the problems.

Additional information and other options are available by typing "man synaptics" in a terminal window.

Or you could search for the Synaptics control program for your GUI and install it. (I use ksynaptics under KDE.)

You may need to add the shared memory options to your xorg.conf file. Here's what mine looks like:

Code:

Section "InputDevice"

        Identifier  "Synaptics"

        Driver      "synaptics"

        Option      "Device" "/dev/input/mice"

        Option      "Protocol" "auto-dev"

        Option      "Emulate3Buttons" "yes"

        Option      "SHMConfig" "true"

        Option      "UseShm" "true"

EndSection
